STEP 1: At first draw a base line of 5.2 cm by scale.
STEP 2: Then from point A draw an arc of radius 7.6 cm and from point B draw an arc of radius 4.7 cm with the help of compass. The intersecting point of both the arcs is C. Join AC and BC.
STEP 3: Now from point A draw an arc of radius 4.7 cm and from point C draw an arc of radius 5.2 cm with the help of compass. The intersecting point of both the arcs is D. Join AD and CD.
